The layering violation is ugly and we don't really need that.
I have a simpler solution by extending srvid_exists().

Also, we need lot more code in various places including tests. :-)
I will post the patches as soon as the protocol changes are upstream.

Meanwhile, I want to fix the implementation of PROCESS_EXISTS.
The patches are attached. Should we backport this to 4.6? (Will need a bug
#.)
